Another of Hillary's lost laptops? Obviously this laptop pre-dates the former First Lady's stint with the State Department, but I can only wonder who might have used it. This Compass II 1219 powered up with custom BIOS ROM. Click image for larger view.

The 1975 RCA COSMAC Microkit. This is the first commercial microcomputer from RCA to contain the two-chip COSMAC microprocessor (TC 1084 / TC 1085 version). The processor was developed in New Jersey, but the kit itself came out of the RCA Palm Beach Division. Click image for larger view.

Note the TC 1085 chip on the processor card, which is the earlier name for the CDP 1801 and has a silk screen date of late 1974. Click image for larger view.

Teletype ASR 33 Papertape reader. You can feed a piece of papertape into the reader in local mode to print a section of tape.

I have found that the trick to splicing, aside from having correction patches is sometimes to overlap two pieces of tape, not try to get an exact cut in the program. To do this I stick in an S0 line (filler line) on both sides of the splice.
If there is a small tear in a tape that causes the reader to snag, use correction patches. If the rip is too large to patch, you'll have to splice it, just as one would a piece of film. Here are some tips how to do this...
Below is a splice of tape, represented by its data. Each 8-bit character is represented by the holes in the tape one at a time as it's fed into">...[ read more ]

This is the Rainbow PC100-B2 I restored from three systems' parts. I used the VR241 display from the previous dead Rainbow PC100-B2's I had been working on and now I finally have a system that works. Click image for larger view.

This will not do....these VR201's are hard to find without screen rot. Click image for larger view.

I got this message from I Primus who suggested ways to deal with the VR201:
"..The cable to the VR201 is very, very simp">...[ read more ]

The cover of the Hitachi HIDIC 100 Mini Computer brochure. Click image for more photos and a pdf of selected photos, not the full brochure

To do...scan the entire brochure. Anyone have info on this computer? I know of other mini's in the HIDIC line but I never read anything about this one. I believe it's an industrial minicomputer sold only in Japan. I need to find a way to optically scan Japanese or find someone who can read Japanese....stand by.">...[ read more ]

Bill Godbout died November 11, 2018 in the "Camp Fire" in Northern California, the worst fire recorded in the history of California. Bill Godbout was an early microcomputer industry pioneer whose company Godbout / Compupro based in the Silicon Valley was known for it's quality products. Godbout started as a surplus electronics parts company that expanded into S-100 bus peripheral card manufacture for MITS Altair and other S-100 systems. Godbout began selling complete S-100 systems in the later 1970's and changed it's name to CompuPro. The CompuPro line of S-100 bus systems were sold well into the mid 1980's.

"...One of the more interesting problems we faced at ROLM MSC (as opposed to
the telecom side) was the fact that all hardware was designed to be
tri-service. Salt spray and fungal resistance required that the cases
be sealed with thermal frames to conduct heat to external heat
exchangers, but that created interesting issues when sticking the box on
an aircraft (but was a lifesaver with disk drives, as otherwise flying
heads had a tendency to crash with altitude). The chassis ended up
being quite heavy due to the hammer and drop tests (as others have
noted,">...[ read more ]

Interesting short article that describes the state of computer firmware in 1967, and recent developments. This is the copy of Electronics that would have been sold on the day of my birth.

The West German-made BASIS 108 was an Apple II clone with a Z80 processor and built-in video features. This unit has 128K RAM. Click image for larger view.

System power checked out, clean inside, boots Apple Pascal OS. No obvious restoration needed. After a more thorough check-out, I will explore the monitor program (6502) and attempt to boot CP/M, and Apple II programs in color.
